Hank Pym is a genius, one of the founding members of the Avengers, the creator of Pym Particles and Ultron, a sufferer of Bipolar disorder and a modern-day superhero. He has acted under many memorable identities such as Ant-Man, Giant Man, Goliath, Yellowjacket, and the Wasp. He is also the Earth's Scientist Supreme, as decreed by Eternity.

I feel like I should be more upset about this... after all, I do like Antman... but it doesn't actually bother me all that much. I'd even be totally fine with Tony Stark creating Ultron; frankly, I think that makes more sense within the Cinematic universe

But even if Hank Pym isn't in the movie physically, that doesn't mean they couldn't still reference him in the movie as being the one who created the artificial intelligence of Ultron and have Tony being the one who weaponized it for S.H.I.E.L.D. or something. They did something similar in Avengers: EMH where both Hank and Tony designed Ultron together and could be what they plan to do here.

But I do think it needs to be taking into consideration that Avengers 2 is still more than a year away, meaning that things Whedon says now could very possible change in the coming months as they move forward with production.

I love Antman, and it sucks that he hasn't been in any of the movies yet. He's a founding Avenger, he needs more screen!

@war_killer: Fair enough, but with his movie slated for after Avengers 2, there doesn't seem to be much hope for him.

Just because his movie is slated after Avengers 2 doesn't mean he can't appear before then. They could easily have him appear in Avengers 2, or simply reference him in the movie, which could lead into his solo film. Not to mention, even though I doubt they will, they could also make Ant-Man as a prequel. There were rumors with Hank Pym having been Ant-Man during like the 70s and with Scott Lang being the modern day Ant-Man, so there are many ways to have Hank Pym appear before his solo movie.
